Plasma-grating-induced breakdown spectroscopy (GIBS) has proven itself superior to filament-induced breakdown spectroscopy (FIBS) in detection of trace elements in soil due to the higher intensity and electron density inside the plasma waveguide. The 2D plasma grating generated by the interference of three n

The presented review summarizes nearly two decades of studies on femtosecond laser-induced breakdown spectrometry (fs-LIBS). When an ultra-short (<1 ps) laser pulse is used for ablation, the physics of laser-induced plasma changes dramatically in comparison with ablation by pico or nanosecond pulses.

In this work, a spark discharge was used to re-excite the plasma induced by a femtosecond laser operated at 1 kHz repetition rate. It was experimentally demonstrated that the spark discharge both prolonged the time durations and enhanced the peak intensities of the atomic emissions of the laser-induced plasm

Keywords: Femtosecond laser, fiber laser, LIBS, explosive material, compact. 1. INTRODUCTION Laser-Induced Breakdown Spectroscopy (LIBS) is a type of atomic emission spectroscopy that involves focusing a pulsed laser beam to generate plasma and excite a sample on the target surface, which can initially be in solid, liquid, or gaseous form.
Laser Induced Breakdown Spectroscopy (LIBS) has emerged as a novel technique that not only resolves issues of versatility, and rapid analysis, but also allows detection in settings not currently possible with existing methods. Several studies have shown that femtosecond lasers may have advantages over nanosecond lasers for LIBS analysis in ...
